Building foundation soil interactions are complex phenomena requiring advanced mathematical and numerical modeling. In this study, the interaction between the super-structure and sub-structure is investigated by modeling the soil as simple as possible to capture the overall response of the system. In the present work effectiveness of modeling in software for determination of settlement behavior of the medium rise building with isolated footing and raft footing in different types of soil considering soil flexibility interaction is studied. The non-linear frame building of 15 storeys is used to study the response of the model in Midas GEN. The simple soil model with isolated and raft foundation is then employed in Midas GTS NX to this nonlinear frame models to quantify the effect of SSI on the overall response of actual structures. The settlement results from Midas GTS NX are compared with the conventional settlement method described by IS: 8009-1976.
